Poco meno di mille dollari: con questa cifra un team di ricerca è riuscito a raccogliere, per anni, traffico satellitare geostazionario non cifrato . È una cifra bassa — e questo è il punto: la vulnerabilità non risiede in hardware esoterico ma in pratiche di configurazione e in assunzioni sbagliate sull’obscurity del mezzo. Come hanno fatto Il principio è semplice: molte stazioni geostazionarie trasmettono segnali che coprono vaste porzioni di superficie; un’antenna direzionale, anche piccola, orientata correttamente riesce a ricevere quei segnali. I ricercatori hanno usato un setup economico, software-defined radio e tool open-source per decodificare e analizzare flussi IP e VoIP. L’operazione è passiva: non si inviano pacchetti né si interferisce — si ascolta. Perché questo è rilevante? Perché la trasmissione on-air non cifrata rimane leggibile a chiunque abbia l’antenna. Non c’è bisogno di attacchi sofisticati o di accessi privilegiati: basta la linea di vista e il know-how ...
World in dangerous drift towards war: Kissinger warns world fast approaching ‘turning point in human history’
IRAN - Former US Secretary of State Henry Kissinger has warned that a crisis involving a nuclear Iran is in the “foreseeable future.” The Nobel Peace laureate, 89, was speaking about prospects in the Middle East at the World Economic Forum. He said nuclear proliferation in the region triggered by an armed Iran would increase the chances of an atomic war – “a turning point in human history. I believe this point will be reached in a very foreseeable future,” he added. He also urged the US and Russia to co-operate in resolving Syria's conflict. “There has emerged in the region, the current and most urgent issue of nuclear proliferation. For 15 years, the permanent members of the United Nations Security Council (UNSC) have declared that a nuclear Iran is unacceptable, but it has been approaching,” he said. In his assessment of the stand-off between Iran and Western powers over its nuclear program - which Tehran argues is for peaceful and civilian purposes – Mr. Kissinger called for “serious” negotiations on both sides to look for solutions. “Unilateral intervention by Israel would be a desperate last resort, but the Iranians have to understand that if they keep using the negotiations to gain time to complete a nuclear program then the situation will become extremely dangerous.” The consequences of Tehran's program, he said, would be that other countries in the region would also want nuclear arms. “The danger is that we could be reaching a point where nuclear weapons would become almost conventional, and there will be the possibility of a nuclear conflict at some point... that would be a turning point in human history,” he said. -BBC
